STRUCTURAL STEEL WELDING ICC
EXAM QUESTIONS AND ANSWERS
GRADED A+ 2026
A welding operator successfully completed performance qualification using multiple SAW
electrodes. Can he weld using a single SAW electrode? - ANS Yes, that does not warrant
requalification

Does the 5G welding position rotate during welding? - ANS No
When using an FCAW reinforcing steel WPS, a requalification.
% increase in amperage requires WPS requalification. - ANS More than 10%
What's the acceptance criteria for a bend test on a stud during stud base qualification? -
ANS Fracture can't occur in the weld or HAZ.
A fillet weld in a tubular connection is specified to measure 1/4-inch in size and 10 inches in
length. What is the minimum allowable fillet weld size? - ANS 5/32-inch for a 1 inch length.
What does HAZ stand for? - ANS Heat affected zone.

,A fillet weld in a tubular connection is specified to measure 7/8-inch in size and 5 inches in
length. What is the minimum allowable fillet weld size? - ANS 3/4-inch for a 1/2-inch length.
A welder's PQR tests successfully pass for a flare-V-groove weld using sheet to sheet steel in the
overhead position. What positions is the welder qualified to weld in? - ANS Flat, horizontal,
overhead
Special inspection tasks and frequencies are found in which publication? - ANS AISC 360
A 1 inch thick test plate is welded with ESW using a CJP groove welds for WPS qualification and
meets acceptance criteria. What plate thickness range is qualified? - ANS 1/2 inch to 1.1
inches
The D1.1 code is intended for which of the following types of steel? - ANS Low Alloy
According to AISC, the Inspector must document acceptance or rejection of how many welded
connections in a structure? - ANS Each One
A welder successfully welds a WPQR pipe test specimen for production CJP Groove Butt Joints
using a 6 inch test pipe with 3/8" thick walls. What is the minimum plate thickness qualified? -
ANS 1/8-inch
What is the maximum fillet weld size along the edge in a lap joint when the base metal is 1/4-
inch thick? - ANS 3/16-inch
A welder was qualified using a backing bar for a CJP groove weld on his WPQR test? Is he
qualified to weld a CJP groove weld joint that does not have backing but does have a qualified
WPS? - ANS No, omitting backing is an essential variable that requires him to requalify if
changed.
